Meaning
Regulatory provisions governing miscellaneous dangerous goods appear within the international maritime organization framework for sea transport of packaged hazardous materials. Ocean shippers consult imdg code section 2.9 to identify classification rules and UN identification numbers for lithium metal and lithium ion batteries. Direct scope covers marine vessel transport in international waters, leaving inland transport standards to regional road or rail authorities.
Class Specification
Maritime safety frameworks designate elevated temperature materials and lithium batteries under class nine dangerous goods. Maritime compliance officers reviewing imdg code section 2.9 assign UN 3480 for standalone lithium ion cells, UN 3481 for cells contained in or packed with equipment, and UN 3090 for lithium metal chemistry. Provisions distinguish prototype cells and production runs, requiring specialized packaging for damaged units capable of rapid thermal reaction.
Packaging Requirement
Outer packaging for class nine shipments must pass structural integrity tests specified under international maritime regulations. Packaging instructions require short-circuit protection on exposed cell terminals and thermal insulation to prevent heat propagation to adjacent cargo.
Maritime Stowage
Vessel operators assign dedicated stowage categories on container ships based on dangerous goods risk levels. Port authorities require lithium battery containers to sit on deck or in ventilated cargo holds away from heat sources and living quarters.
